`chrome_settings_overrides` キーは次のプロパティを持つオブジェクトです:

| 名前 | 型 | 説明 |
| --- | --- | --- |
| `homepage` | `String` | Defines the page to be used as the browser's homepage.
The replacement is given as a URL. The URL may:* point to a file bundled with the extension, in which case it is
 given as a URL relative to the manifest.json file
* be a remote URL, such as "https://developer.mozilla.org/".

 If two or more extensions both set this value, then the setting from
 the most recently installed one will take precedence.

To override new tabs, use "chrome\_url\_overrides" instead.

 This is a
 localizable property.
  |
| `search_provider` | `Object` | Defines a search provider to add to the browser.

 The search provider has a name and a primary search URL. Alternative
 URLs may be provided, including URLs for more specialized searches
 like image search. In the URL you supply, use
 "`{searchTerms}`" to interpolate the search term into the
 URL, like:
 `https://www.discogs.com/search/?q={searchTerms}`. You can
 also provide POST parameters to be sent along with the search.


 The search provider will be presented to the user alongside the
 built-in providers. If you include the
 `is_default` property and set it to `true`, the
 new search provider will be the default option. By supplying the
 `keyword` property, you enable the user to select your
 search provider by typing the keyword into the search/address bar
 before the search term.


 This is an object with the properties listed below. All string
 properties are
 localizable.


`name`
String: The search engine's name, displayed to the user.
`search_url`
String: URL used by the search engine. This must be an HTTPS URL.
